Reference Intervals for Schirmer Tear Test and Intraocular Pressure in Healthy Hamdani Crossbred Sheep

open access: yesVeterinary Medicine and Science, Volume 12, Issue 4, July 2026.
This study establishes reference intervals for Schirmer tear test (STT) and intraocular pressure (IOP) in healthy Hamdani crossbred sheep. STT values were lower and IOP values higher than previously reported, highlighting the importance of breed‐specific reference ranges in clinical ophthalmic evaluation.

Ocular Pharmacokinetics of Topical Chloramphenicol in Dogs: Effects of Concentration and Vehicle Formulation

open access: yesJournal of Veterinary Pharmacology and Therapeutics, Volume 49, Issue 4, Page 378-384, July 2026.
ABSTRACT This study compared tear film exposure and retention of four chloramphenicol ophthalmic formulations in dogs, evaluating the effects of drug concentration (0.2% to 5%) and vehicle type (solution vs. ointment). Eight healthy dogs were enrolled in a randomized paired‐eye crossover study consisting of two sessions with a 7‐day washout.
